s'PEcrFircA'rIoN forming part of Letters Patent No. esama'dated August 7,1883.

Application tiled July 28. 1832. (No model.)

To all whom i315 may concern.-

Be it known that I, GEORGE HENRY A. HAcKsTADT, a citizen of the United States, rersiding at Ludlow, in thecounty of Kenton and State of Kentucky, have invented a new and `useful Spoke-Tenoning Machine, of which the following is a specication. l

My invention relates to that class of spoketenoning machines'which are used in small or ro repair shops, and which, whenbeing used, are

attached 'to a single spoke of the wheel.

The objectof my invention isy to improve such a spoke-tenoning machine southat it will be better adapted to the wants of the wheelwright, by enabling him to use not only the various sized hollow kangers which may be sold along with this machine, but also any hol- `low angers which he may already have or prefer which are or can be used in spoke-ten-` oning machines; also, by so constructing this spoke-tenoning machine anda bench-vise relative to each other that the tenoning-maehine, when combined with and attached to said vise, may furnish the wheelwright with a ma- 2 5 chine which may serve various other purposes for which additional machines might be required-as, for instance, drilling, boring, cutting threads, tapping, Src.; and since the said spoke-tenoning machine and the vise may be 3o used for their separate purposes at the same time such a combined tool would be' very desirable in small or repair shops. p

In the drawings, Figure l shows my spoketenoning machine in position attached to a spoke, as when'it is used for tenoning spokes. Fig. 2 shows the clamp C, used for securing the device to a spoke, Fig. 3 `shows an end view of one of the spoke-standards sa. Figs.

\ 4 and 5 `show two different methods ofattach 4o ing thehand feed-lever L to the hollow augershaft4 S. Fig. 6 shows the spoke-tenoning machine attached tothe bench-vise as it is to be when to-be used for such additional purposes as mentioned. Fig. 7 shows a plan of theA beneh-vise and apart of the spoke-tenoning machine as attached thereto. Fig. Sshows an end view of the vise and asection of the frame F. Figs. 6, 7, and 8 show how the said devices are attached to 5o bench. b

In Fig. l, F is the main supporting-frame of the machine. One end of frame F carries two` each other and to the inward to an abrupt shoulder, q. Said metal `V-b'earings may be placed in contact with the standards, ss ss, which are attached thereto by means foi nuts, and which have bearings at their ends for a spoke, Sp. fram'eF for said standardsare not tapped, since, if they were, the threads would be injured in bolting the frame to the bench-vise, and hence threads are not out on Ythat part of the standards ss ss which is within frame F. 6o

`By referring to Fig. 3 also it can be seen that the bearing ends m of said standards have V- shaped bearing-surfaces for `the spokes, and sides tapered from the extremities of a standard spoke; or, as I think better, pieces of leather or rubber can be pressed over and into these V bearings and lapped down upon the sloped sides m, and secured by means of bands or rings 7o r, driven down over the leather or rubber to a tight position adjacent the abrupt shoulder gb, and hence present a bearing-surface to the spoke that will not abrade or disflgure it. I may also make argroove around two or all of 7 5 thesides of a standard adjacent shoulder, q, and beneath the ring i', so that the leather, which is soaked before putting in place, or the rubber, may be pressed into said groove and may be more securelyheld in position. Leather or rubber may be put around and be sewed or y otherwise attached to clamp C for the same branches n u of a clamp, C, which, in connec` tion with the spoke-standards `as ss, serves to bind theV frame F to the spoke, and said 9o branches, after straddling F, unite above it in `a boss, mi, which'is tapped,`and forms a nut for a binding-screw, bs, provided with a tailnutgtt, which is used for tighteningl or loosening the clamp when the machine is attached 9 5 to or loosened from a spoke. To the other end of frame F are attached adjustable standards provided with bearings `I3 B for the hollow auger-shaft S. Said shaftis cylindrical, and the shank of a hollow auger or a socket-piece, so, for an auger or for a chuck', as ch, may be attached to its inner end, as indicated, and a journal be provided upon such auger-shank, socket-piece, or chuck such as will fit in the Ico The holesin 55V v bearings B, having standards with screws s',

Zio

bearing B, and when required different-sized may be used. A collar-stop, @,'serves to regu.- late the length of tenon cut. To the shaft there is attached a handle, h. The shaft-standard at the end of frame F is adjustable in the direction of its length only, and is secured in position by a nut, a, below frame F, and by a tail-nut, tt, aboveit. The :middle portion of frame F is bent, as shown, and has a longitudinal slot, SZ, in which a thimble-nut, n',

projects and along which it can be adjusted, and through said nut a passes the screw s of the standard-supporting bearing B, and by means of this nut n and the tail-nut tt said standard is secured to frame F. By means of slot SZ, the thimble h, and tail-nut tt bearing B may not only be adj usted in the direction Vof the length of its standard, but also in the direction of thc length of frame F. A handlever, L, is attached at one end by a screwpin, p', to a collar on shaft S, and has a longitudinal slot, s, for a fulcrum-pin, p, which-Y is screwed into frame F, and I may place slot s at the end of lever L instead of at the middle, as shown. One method of attaching lever L to shaft S, so as not to interfere with the rotation of said shaft, is shown in Fig. 4, and another in Fig. 5. j

In Fig. 4 a sleeve having a collar, c, is attaehed at any desirable point on the shaft by means -of the binding-screw bs. This sleeve has a groove, g, cut around it, and a thimble which lits on this sleeve has a screw-pin, p, which passes through it and into the groove g of the sleeve, and the other end of which serves as a pin, to which is attached the end of the lever L. In Fig. 5 a sleeve, SZ, is similarly attached to shaft S by means of bindingscrew bs. This sleeve has a groove, g, around it, and a second sleeve, sv, is slotted from the side, so that when sleeve SZ is inserted sidewise into sleeve sv and shaft S is passed through both, the partial circular inward projection ofso being then within groove g of sl, said projection will prevent an endwise movement of sb, while vsleeve sl and shaft Si will be-free to rotate within it. The lever L is then attached to sleeve sv by means of a screw-pin, p.

Now, when it is" desired to attach the inachine just describedto a bench-vise, the spokestandards ss ss are removed and the machine is turned bottom side up, as shown in Fig. 6, and if desiredpins p and p may be loosened and the lever L turned end for end, so as to be more convenient to use. It is preferable to fasten the vise to the right end and corner of the bench, so that the machine may project from the work-bench in the direction of its length, as shown in Figs. 6, 7 and 8.

The bench-plate I), which is secured to bench Ba by bolts Pb, is so made that the fastening end of frame F fits upon said plate and between lugs Z Z Z thereof, and can be firmly secured in place by means of two bolts, Fb,

which pass through the same holes in said frame that the spoke-standards formerly did, and through the vise-plate and bench, and consequently secure the whole device rmly to the bench.

The vise -jaws @j have V-bearing bases j which slide in V-grooves formed by the lugs Pv Po of the vise-plate, and at right angles to the center line ofb shaft S, and a boss, bs, is

cast to the vise-plate in the line of said grooves,

in which rotates a right and left screw, Us, which passesthrough the vise-j aws and serves, when rotated by means of handle h', to open or close the vise. The screw is prevented from moving endwise by means of collar c and handle-boss o. The faces of the jaws may be parallel vertically, and may be continuous, or may have angular or other shaped notches cut in them, as indicated by the dotted lines;r or special known clamping devices may be placed upon and between the jaws for holding round A or other shaped work.

The frame F is inserted endwise and beneath vise-screw fus into its position, and by giving it a wedging fit it may be driven tightly into position, so as to make the whole device more rigid. In fact, it could'in a great measureY be Secured in position by making it and the groove through which it is driven dovetailed in cross-section, so that for some purposes where this arrangement of the machine l have been invented and patented embodying certain features found in my improved spoketenoning machine. Said features are embodied` in a patent for spoke-tenoning machines, granted to John lVIcGune, June 26, 1847 for 'spoke-tenoning machines, to RNV. Eaton, February 26, 1878, No. 200,649, for spoke-tenoning machines, to T. Connor, February 10, 1880, No. 224, 393, and for spoke-tenoning machines, to C. B.
